  Pioneer 11
However, because Pioneer 10 had achieved all its main mission objectives at Jupiter, Pioneer 11 was put on a trajectory by mission controllers that used Jupiter as a gravitational slingshot to redirect the probe on a course toward Saturn.
Pioneer 10 and 11 were recommended by the Space Science Board of the National Academy of Sciences in 1968 as low-cost exploratory missions to the giant planets Jupiter and Saturn, approved by NASA in February 1969, and launched three and four years later, respectively.
Pioneer 11 is headed in the direction of Aquila and may pass relatively near Lambda Aquila in about 4 million years.

 Pioneer Plaque
The key to translating the plaque lies in understanding the breakdown of the most common element in the universe - hydrogen.
This element is illustrated in the left-hand corner of the plaque in schematic form showing the hyperfine transition of neutral atomic hydrogen.
The plaque was designed by Dr. Carl Sagan of Cornell University and drawn by his wife, Linda Salzman Sagan.

 Pioneer 10
Launched on March 2, 1972, Pioneer 10 was the first spacecraft to travel through the asteroid belt, the first spacecraft to make direct observations of Jupiter and in 1983, it became the first man-made object to leave the solar system when it passed the orbit of Pluto.
Pioneer 10 was eleven light-hours away at this point, and so it was twenty-two hours later when researchers at the network's facility in Madrid, Spain, heard Pioneer's response.
As of February 5, 2002, Pioneer 10 was 79.66 AU from the Sun.

 Pioneers 6-11
Pioneer 10 maintained an almost constant view relative to Jupiter for several hours during the closest approach because its direction of travel was the same as the rotation of Jupiter.
Pioneer 11’s views of the planet were quite different to Pioneer 10, because its direction of travel was the opposite to the rotation of Jupiter, travelling a full circle of longitude of the planet during its observations in the four hours around periapsis.
Pioneer 10 had some heating problems for several weeks after launch, so the spacecraft was commanded to point slightly away from the Sun so the shadow of the dish antenna shielded vulnerable parts such as the batteries.

 Pioneer 11
